aec9c13c52 eal: add function to release internal resources
This commit adds a new function rte_eal_cleanup().
The function serves as a hook to allow DPDK to release
internal resources (e.g.: hugepage allocations).

This function allows DPDK to become more like an ordinary
library, where the library context itself can be initialized
and cleaned up by the application.

The rte_exit() and rte_panic() functions must be considered,
particularly if they should call rte_eal_cleanup() to release any
resources or not. This patch adds the cleanup to rte_exit(),
but does not clean up on rte_panic(). The reason to not clean
up on panicing is that the developer may wish to inspect the
exact internal state of EAL and hugepages.

b5ece77212 ethdev: introduce device removal event
This new API allows reacting to a device removal.
A device removal is the sudden disappearance of a device from its
bus.

PMDs implementing support for this notification guarantee that the removal
of the underlying device does not incur a risk to the application.

In particular, Rx/Tx bursts and all other functions can still be called
(albeit likely returning errors) without triggering a crash, irrespective
of an application handling this event.

82cb88375c ring: remove the yield when waiting for tail update
There was a compile time setting to enable a ring to yield when
it entered a loop in mp or mc rings waiting for the tail pointer update.
Build time settings are not recommended for enabling/disabling features,
and since this was off by default, remove it completely. If needed, a
runtime enabled equivalent can be used.

4b5062755a mempool: allow user-owned cache
The mempool cache is only available to EAL threads as a per-lcore
resource. Change this so that the user can create and provide their own
cache on mempool get and put operations. This works with non-EAL threads
too. This commit introduces the new API calls:

    rte_mempool_cache_create(size, socket_id)
    rte_mempool_cache_free(cache)
    rte_mempool_cache_flush(cache, mp)
    rte_mempool_default_cache(mp, lcore_id)

Changes the API calls:

    rte_mempool_generic_put(mp, obj_table, n, cache, flags)
    rte_mempool_generic_get(mp, obj_table, n, cache, flags)

The cache-oblivious API calls use the per-lcore default local cache.

4a22e6ee3d doc: refactor figure numbers into references
This change adds automatic figure references to the docs. The
figure numbers in the generated Html and PDF docs are now
automatically numbered based on section.

Requires Sphinx >= 1.3.1.

The patch makes the following changes.

* Changes image:: tag to figure:: and moves image caption
  to the figure.

* Adds captions to figures that didn't previously have any.

* Un-templates the |image-name| substitution definitions
  into explicit figure:: tags. They weren't used more
  than once anyway and Sphinx doesn't support them
  for figure.

* Adds a target to each image that didn't previously
  have one so that they can be cross-referenced.

* Renamed existing image target to match the image
  name for consistency.

* Replaces the Figures lists with automatic :numref:
  :ref: entries to generate automatic numbering
  and captions.

* Replaces "Figure" references with automatic :numref:
  references.

fc1f2750a3 doc: programmers guide
The 1.7 DPDK_Prog_Guide document in MSWord has been converted to rst format for
use with Sphinx. There is an rst file for each chapter and an index.rst file
which contains the table of contents.
The top level index file has been modified to include this guide.

This document contains some png image files. If any of these png files are modified
they should be replaced with an svg file.

This is the sixth document from a set of 6 documents.
